dmi_intel_rsd_cpuid_leaf

Synopsis

#include <opendmi/entity/intel-rsd/processor-cpuid.h>

typedef struct dmi_intel_rsd_cpuid_leaf {
    uint32_t leaf;
    bool has_subleaf;
    uint32_t subleaf;
    uint32_t eax;
    uint32_t ebx;
    uint32_t ecx;
    uint32_t edx;
} dmi_intel_rsd_cpuid_leaf_t;

Description

The dmi_intel_rsd_cpuid_leaf_t structure holds one CPUID leaf of a processor CPUID information structure of Intel Rack Scale Design (RSD) firmware: the input the CPUID instruction has been executed with, and the values of the registers it has returned. The input is not stored in the structure; the decoder fills it in from the list of leaves of the subtype.

The elements are held in the leaves array of dmi_intel_rsd_processor_cpuid_t, and live as long as the context the structure has been decoded in.

Fields

leaf

Leaf number, the value of EAX the instruction has been executed with.

has_subleaf

Set if the leaf has been read for a given subleaf.

subleaf

Subleaf number, the value of ECX the instruction has been executed with. Meaningful only if has_subleaf is set.

eax

Value of EAX returned by the instruction.

ebx

Value of EBX returned by the instruction.

ecx

Value of ECX returned by the instruction.

edx

Value of EDX returned by the instruction.
